Abstract:
An approach to localization in an indoor environment makes use of a multiple antenna receiver (e.g., in a smartphone, tablet, camera) and knowledge of locations of one or more radio transmitters, which may be part of a data communication infrastructure providing data communication services to devices in the environment. Successive measurements of transmissions from the transmitters are recorded at the receiver as the device is translated and rotated in the environment. Rotation related measurements are also made at the device. The radio frequency and rotation related measurements are used to infer the location and orientation, together referred to as the pose, of the device. Phase synchronization of the transmitters and the receiver are not required. In general, accuracy of the pose estimate far exceeds that achievable using radio frequency measurements without taking into consideration motion of the device, and far exceeds that achievable using the inertial measurements alone.
